I believe that I still have the original drums and rotors still on my 69Z. What would be correct part numbers? When I replaced the ball joints a few years ago, they were still riveted in place.

I'm curious as the car shows aprox 60K on odometer. Could the mileage be 60K or so based on the car having the original drums, rotors (2pc) and rivted ball joints? What are the chances of these three things surviving all these years? I've had the car for 10 years.
